[RFC PATCH 3/3] riscv: dts: starfive: jh7110-pine64-star64: force no USB overcurrent

[Icenowy Zheng]

The Star64 board has no GPIOs to indicate USB overcurrent, however the
USB controller would stop to work if the overcurrent_n signal it gets is
low (which means overcurrent situations happening because of the _n).

Use the pin controller to force the overcurrent_n signal to be high in
order to ensure stable behavior of the USB controller.
